VCOM Mode:
This setting is a pull-down menu in which the user can select the
Operation
Mode
of the serial device connected through this VCOM port as shown in Fig. 3.15. Its
definition is analogous to the one in 3.7.2. Here you can choose whether your serial device
conforms to a RTU or an ASCII message format and can select whether your serial device
is a Modbus slave node or a Modbus master node. Fig. 3.14 depicts the
RTU Slave
mode
which means that a serial device connected through VCOM 1 port will assume a Modbus
slave role and communicate using Modbus/RTU protocol. However, if a master mode
(either RTU or ASCII) is selected, the options for the master mode will be the same as the
slave mode. The only difference is the serial device’s function.
